Hi I have updated our database from koha 21.11.10 to the current Koha 23.11.04. When searching the catalogue I get a result list, but when clicking a single hit I get an error 500. In file "plack-error.log" I have found the following line which could be the reason: DBIx::Class::Storage::DBI::_dbh_execute(): DBI Exception: DBD::mysql::st execute failed: Unknown column 'issue.renewals_count' in 'field list' at /usr/share/koha/lib/Koha/Objects.pm line 317 In fact there is no table "issue" in Koha 23.11, the correct name of this table is "issues" (see https://schema.koha-community.org/23_11/tables/issues.html). I have searched in Bugzilla but couldn't find a respective bug. But I found the sequence "issue.renewals_count" in https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=137152 so there may be some relation to https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=30275 Does anyone know how I can solve this problem with the 500 error?
